This invention relates to a knife holding attachment for grinding machines such as used, for example, in sharpening or hollow grinding the knives of sausage machines.

It is an object of the invention to provide a simple form of attachment which can be connected readily to the base of a grinder and can be adjusted to hold each of the blades of a sausage machine at a predetermined angle relative to the periphery of the grind stone so that each blade can be ground along either edge or can be'hollow ground.

l/Vith the foregoing and other objects in View which will appear as. the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment ofthe invention herein disclosed may bemade within the scope of what is claimed without departing from the spirit of the invention.-

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings,

Figure 1 is a front elevation of the attachment in position to hold .a blade against a grindstone, said blade being supported by the holder.

Figure 2 is a side elevation of the holder and blade and a portion of the grindstone.

Figure 3 is a section on line 3-3, Figure 1, showing another position of the blade relative to the periphery of the grindstone.

Referring to the figures by characters of reference, 1 designates the base of a motor 2 to the shaft of which is connected a grindstone 3. Attached to the base 1 is a sleeve 4 in which 40 is slidably and rotatably mounted a rod 5 having an arm 6 extending radially from' one end. To this arm is pivotally connected an ear 7 extending from a plate 8, a bolt 9 being utilized'as a pivot for the ear 7 and constituting means whereby the plate can be held at any desired angle relative to the arm 6. V 1

Extending through the plate 8 is a clamping bolt 10 providedwith a wing nut 11 or the like and this bolt is adapted to extend blade.

through the central opening of a set of radially disposed knives 12 such as used with sausage machines. It will be noted that the plate 8 has a straight edge 13. This edge is so located that when the blades 12 are mounted on the bolt 10 two oppositely extending blades will have edgesregisteringwith the side edge 13 of the plate at which time the remaining blade will be extended at right angles to the plane of rotation of the grindstone 3.

By loosening the bolt 9 the arm 6 can be adjusted angularly' relative to the ear 7 so that the supported blade 12 can thus be heldat any desired angle to the periphery of the grindstone 3. For example, and as shown in Figure 2, the plateS can be so arranged as tohold the intermediate portionof the laterally extending blade 12 against the periphery ofthe grindstone so that said blade will be hollow ground. By making another vadjustment such as shown, for example, in

Figure 3, the blade can be so'held relative to the periphery of the wheel as to cause the back edge portion thereof to be ground.

After the parts have been adjusted to the relative positions necessary to insure grinding of the blades at the proper angle, the

plate 8 can be swung about the longitudinal axis of the rod-5 so as to bring the laterally extending blade 12 against the periphery of the grindstone 3. While the blade is thus held the rod 5 can be slid longitudinally back and forth so that in this way all portions of the surface to be ground can be presented to the grindstone. Thereafter the bolt 10 is loosened, another blade is swung therearound to laterally projecting position and the bolt is tightened. The parts are thus positioned for proper grinding of the newly resented ably and rotatably mounted, a radial arm thereon, a plate connected to the arm and ad- In every instance the bla e can be properly positioned relative to the plane of justable angularly relative thereto about an axis parallel with the axes of rotation of the rod and grind stone, and means on the plate for gripping a set of integral, radially disposed blades of a sausage machine to present one blade to the periphery of the grind stone at any predetermined angle relative to said periphery, one of the edges of the holding plate constituting a gauge for determining the correct position of the blade to be sharpened.

In testimony that claim the foregoing as my own, I have hereto afliXed my signature.
